Spintronics

The remarkable trend in electronics described by the Moore law is today experiencing increasing difficulties due to fundamental limitations in the current miniaturization approach. Alternative strategies need to be developed, e.g. exploiting a bottom-up molecular approach, mesoscopic devices, additional degrees of freedom or quantum physics. In this frame, spin is likely going to play a crucial role to carry classical or quantum information. Spintronics research in Lecce addresses different fields, from nanoscale devices based on magnetic molecules or nanoparticles to magnetic multilayers and more recent activities on RF systems for hybrid spintronics. Furthermore, we also investigate novel materials (such as multiferroics and functional oxides) and perform magnetic and ferroelectric characterizations. More in detail:

NanoElectronics/Spintronics

This research was the starting point for the group, thanks to the EU project SpiDME. To interconnect the individual building blocks at the nanoscale, we employ electron beam lithography (EBL), focused ion beam or a non- conventional method based on the selective wet-etching and oxidation of an AlGaAs/GaAs quantum well structure for the simultaneous fabrication of large arrays of nanodevices. Molecules or nanoparticles are typically positioned by specific immobilization procedures exploiting suitable functional end-groups. Charge and spin transport studies are carried out within superconducting magnets up to 10.5T and down to 10 mK.

Nanomagnetism

Nanomagnetism in magnetic materials and nanoparticles is investigated by vibrating sample magnetometry and a.c. susceptibility. Beyond hysteresis, both zero-field cooled and field cooled curves are typically acquired to evaluate the blocking temperature.

Magnetic Multilayers

Multilayer structures are the basis for giant or tunneling magnetoresistance devices. Our research focuses on the integration of further layers including nanoparticles, magnetic molecules, multiferroics or superconducting films. On the technological side, the target is to achieve a large magnetoresistance, which is useful for further applications such as in biosensors.

RF systems for hybrid spintronics

Recently, we started to investigate 3D microwave cavities and SAW devices for their integration in hybrid spintronic architectures where photons and phonons are coupled to the magnetic degree of freedom.

Multiferroics and Functional Oxides

Here we investigate high-k materials for gate stack technology in logic and memory devices and multiferroic materials for implementing novel operational concepts in spintronics exploting magnetoelectric coupling. Structural, morphological and dielectrical characterizations are typically carried out, while ferroelectric and multiferroic properties are investigated by means of PFM, KPFM, Dielectric and Ferroelectric (PUND) measurements.

Technology Trasfer in Nanotechnology

Technology Transfer in Nanotechnology: Challenges and Opportunity

Lecce, 18/19 ottobre 2018

CNR NANOTEC c/o Campus Ecotekne

JRC in collaboration with the National Research Council (Cnr) is organising a workshop on Technology Transfer in Nanotechnology,

which will take place in CNR Nanotec (Lecce, Italy) on 18 and 19 October. This workshop is organised in the framework of the TTO-CIRCLE initiatives.   The aim of this event is to explore how technology transfer activities can be used as a mechanism to help EU industry, particularly Start-ups and SMEs, and Government in deploying and adopting Nano-technology. Practical examples will be presented to illustrate the potential of technology transfer in this area.   The workshop will gather technology providers, industry executives, technology transfer officers, policy makers and financial intermediaries to share experiences and lessons learned. One of the key objectives is to discuss policy implications at all levels that could help accelerating the adoption of Nanotechnology by the European manufacturing industry.

Nanotechnology Transfer Day

26 Luglio 2018 - Lecce

CNR NANOTEC c/o Campus Ecotekne Siglato l’accordo lo scorso maggio tra CNR NANOTEC e Pairstech Capital Management, ha preso il via la collaborazione con PhD TT per la valutazione della ricerca

E’partita la collaborazione con PhD TT per la valorizzazione della ricerca sulla base dell’accordo siglato lo scorso Maggio tra CNR NANOTEC e Pairstech Capital Management, società di gestione patrimoniale che fornisce agli investitori istituzionali e privati un insieme di veicoli di investimento, al fine di valorizzare i risultati della ricerca svolta all'interno dell'Istituto.

Giovedì 19 Luglio dalle ore 11 alle ore 14 nella sede del CNR Nanotec di Lecce si è tenuto un incontro sul trasferimento tecnologico nel settore delle nanotecnologie applicate al settore biomedicale.

L’evento è stato organizzato dall’ufficio di Trasferimento Tecnologico del CNR Nanotec che ha inaugurato con questa giornata un ciclo di eventi mirato a presentare agli attori dell’ecosistema dell’innovazione nel settore delle nanotecnologie i vari modelli e alcune best practice di trasferimento tecnologico. In questa prima giornata il dott. Heber Verri e la dott.ssa Paola Urbani hanno presentato il nuovo modello di trasferimento tecnologico PhD TTãIndex Model.

PhD TT è una realtà italiana completamente indipendente specializzata in trasferimento tecnologico, è un acceleratore organizzato per il Go to Venture Practice, orientata al mondo delle Lifes Sciences.

PhD TT ha sviluppato un nuovo modello di trasferimento tecnologico: il PhD TT©INDEX MODEL dedicato alla generazione di valore dell'innovazione, focalizzato alla riduzione dei rischi delle opportunità di investimento a sostegno della ricerca.

I ricercatori intervengono attivamente nell'analisi iniziale di fattibilità e nella costituzione della futura società (start-up), con l'obiettivo di attrarre capitale di rischio utile a sostenere la fase del trasferimento tecnologico nella visione della "Research for go-to-market".

Il modello PhD TT nasce da un bisogno del mercato, quello di far dialogare due mondi estremamente diversi tra loro: il mondo della ricerca e il mondo degli investimenti.

PhD TT supporta tutte le attività in collaborazione con il TTO - CNR Nanotec con un team di lavoro esperto e grazie a un comitato scientifico-economico qualificato.

In occasione dell'evento del 19/7 u.s. al CNR Nanotec di Lecce, PHD TT ha presentato il proprio track record, dove si sono potuti valutare in dettaglio i casi di successo di intervento del PhD TT©INDEX MODEL.

Disordered serendipity: a glassy path to discovery

A workshop in honour of Giorgio Parisi’s 70th birthday

September 19-21, 2018 - Roma

Sapienza University

With the occasion of celebrating Giorgio Parisi 70th birthday, the conference "Disordered serendipity: a glassy path to discovery" brings to Rome many among the world-leading experts in the field of complex systems. In order to properly represent the many fields of research where Giorgio Parisi gave a relevant contribution in his studies of disordered systems, the conference covers a broad spectrum of topics: from  fundamental and rigorous analysis of the statistical mechanics of disorder systems to applications in biology and computer science. These subjects are deeply interconnected since they are characterized by the presence of glassy behavior.
